Submarine Cable Map: 93 of the world’s major submarine cable systems and 28 planned systems that are due to enter service by 2011.
It's a Small World, Afterall: researchers at the European Commission's Joint Research Centre in Ispra, Italy, and the World Bank, created this gorgeous map. They first created a model, which calculated how long it would take to travel from a given point, to the nearest city of 50,000 people or more; the model includes rail, road, and river networks.
Then they plotted these results on a color coded map: The brighter an area, the closer it is to a big city; the darker it is, the further out it is. (The blue lines above represent oceanic shipping lanes.)
